The Lowdown
Alright folks, Rusty here. Let’s get straight into it. We’ve got a solid run of surf shaping up at Lakey Pipe, and honestly, it’s looking like a great stretch for anyone who can handle a bit of size.
The opening days are a slow burner. Tuesday the 25th starts with some chest-high swell from the SSW, around 5ft, but the wind is a moderate cross-offshore breeze, keeping things reasonably clean. The wave energy is there (1121), but it’s not quite firing on all cylinders yet. Wednesday the 26th steps it up a notch with similar 6ft swell from the SW, a longer 14-second period, and lighter winds. The surf is clean and the energy is moderate (1212), making it a solid intermediate day.
Now, the real standout comes on Friday the 28th. That’s your call-to-work day. We’re looking at a solid 8ft swell from the SW with a 17-second period, pounding into the reef. The wave energy is pumping hard at 4343, and with light, cross-offshore breezes, the wave faces will be picture-perfect. This is a serious groundswell, and for a reef setup like Lakey, it’s going to be a proper session. The crowd factor is “often,” so expect plenty of company out there, but for good reason. This is expert territory – 8ft is no joke, so you’ll need your wits about you.
The run continues strong into the weekend. Saturday the 29th holds at 7ft, still clean. Sunday the 30th drops a touch to 5ft, but the period stays solid. Monday the 31st brings a fascinating spike in period – 20 seconds from the SSW – with 4ft swell. That’s a very long-period groundswell, which will unload a lot of energy (1610) on the takeoff, and the sets will be clean and lined up. The light winds will keep it smooth.
Into the first week of September, the swell stays on. Tuesday the 1st and Wednesday the 2nd are both solid 7ft, with calm winds and excellent conditions. The water temperature is about average for this time of year, so no surprises there.
The second week starts to fade a little, but there’s a late pop. The 4th and 5th of September are smaller, around 5ft, and the winds are a little more side-on, but it’s still surfable. Then, look at the 8th and 9th of September. That Tuesday the 8th has a 22-second period from the SSW with 4ft, and the afternoon jumps to 7ft with a 20-second period. The wave energy is massive (3972). Wednesday the 9th sees 8ft swell again with a 17-second period and 3608 energy. It’s over a week away, so chalk it up as a promising bet, but the signals are strong.
Bottom line: Friday the 28th of August is your absolute best bet for a clean, powerful, expert-level session. The 8th and 9th of September are the long-range prizes. Get on it.
Rusty.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
